Sad cabbies: check out these pictures of anxious London taxi drivers

If you thought you were having a bad day, spare a thought for these poor London cab drivers who look so unhappy and anxious it's almost enough to make you delete your Uber app on the spot. With London's black cabs facing tough times, photographer Oleg Tolstoy has been snapping pictures of sad cabbies for his new exhibition 'Who's Driving You'.

Black cab drivers have been campaigning for Transport for London to impose stricter regulations on private hire car companies, including Uber. Around 300 cabbies have been protesting again today outside and inside City Hall during the Mayor's Question Time - and police were eventually called to remove them from the building after Boris Johnson called them 'luddites'. Nice.
